BACKGROUND Position-dependent gene silencing in yeast involves many factors, including the four HIR genes and nucleosome assembly proteins Asf1p and chromatin assembly factor I (CAF-I, encoded by the CAC1-3 genes). Both cac Delta asfl Delta and cac Delta hir Delta double mutants display synergistic reductions in heterochromatic gene silencing. However, the(More)
By using two-dimensional polyacrylamide gel electrophoresis, a proteomic analysis over time was conducted with high-cell-density, industrial, phosphate-limited Escherichia coli fermentations at the 10-liter scale. During production, a recombinant, humanized antibody fragment was secreted and assembled in a soluble form in the periplasm. E. coli protein(More)
